Interaction of a monochromatic ultrasonic beam with a finite length defect at the interface between two anisotropic layers: kirchhoff approximation and fourier representation


This paper presents a fast computation method to simulate the interaction between a bounded acoustic beam and a 2-layered anisotropic structure with a finite defect on the internal interface. The method uses the classical Fourier decomposition of the fields into plane waves, and the Kirchhoff approximation is introduced to calculate the diffusion by the… (More)
